WORK-HOLDING CLAMP.

SPECIFICATION forming part of Letters Patent No. 242,959, dated June 14,1881,

Applicationfiled April18 ,1881. (NomodeL) To all whom it may concern:

Be it known that I J OSEPH M. NAGLEE, a citizen of the United States,residingin Philadelphia, Pennsylvania, have invented certainImprovements in Work-Holding Clamps, of which the following is aspecification.

My invention relates to clamps for holding strips of wood together untilthe glue used for uniting them has become sufficiently set, the objectof my invention being to combine inone instrument means for holding oneor more strips, and for clamping to the same another strip or strips, aslully explained hereinafter.

In the accompanying drawings, Figure 1 is a perspectiveview of one formof my improved clamp; Fig. 2, an edge view of the same, and

Figs. 3 and 4 views showing other forms of the clamp.

The clamp shown in Fig. 1 consists of a metal yoke, A, each arm a ofwhich terminates in a hub, vand through each hub passes aclamping-screw, b, the two screws of the arms being in line with eachother. A third screw, d, arranged at right angles to the screws 1) 1),passes through the central hub, e, of the yoke midway or thereaboutbetween the two arms.

One of the uses of this clamping device is illustrated in Fig. 1,.whereD represents a strip of wood, to which another strip, E, has to beglued. The strip D is firmly held by and between the two screws 1) binsuch a position that one edge of the strip D is directly opposite theend of the screw d, so that after a proper application of glue the stripE may be held by the screw 61 against the edge of the strip D until theglue has become properly set, the screws 12 b retaining the strip D sofirmly that it will not yield under the action of the screw d.

The strips of wood may be of such a length as to demand the use of twoormore clamps A.

desirable to glue two strips of wood arranged at right angles to eachother to a third strip held by and between the screws 1) b.

While the clamp has been designed for use in making small woodenstructures-such, for instance, as those made by amateurs by the aid ofscroll-saws-it may be made on a large enough scale to be used bycarpenters and cabinet-makers.

I prefer to make the clamps of malleable cast-iron.

I claim as my invention- 1. Ihe within-described clamp, consisting ofthe metal yoke A, provided with a screw, d, and having arms (6 a, unitedatone end only of theyoke, each arm being provided with a screw orscrews, b, the screw or screws of one arm being in line with the screwor screws of the other arm and at right angles to the screw d, allsubstantially as set forth.

2. Thecombination of the yoke, its'screw d, r
